A system includes a hydrocyclone liner. The hydrocyclone liner includes a head section having a fluid inlet formed in a first sidewall of the head section and an overflow outlet. The hydrocyclone liner also includes a separation section having an underflow outlet. A sleeve is disposed about at least a portion of the head section, a portion of the separation section, and an interface between the head section and the separation section.

Joint support system for hydrocyclone liner

A system includes a hydrocyclone liner. The hydrocyclone liner includes a head section having a fluid inlet and an overflow outlet. The hydrocyclone liner also includes a separation section having an underflow outlet and a first sidewall. A diameter of the separation section of an outer surface of the first sidewall is constant along a length of the outer surface of the first sidewall. The head section and the separation section are joined together via a bond at an interface between the head section and the separation section. The hydrocyclone liner includes a sleeve disposed about at least a portion of the head section, the separation section, and the interface. The sleeve is configured to hold the head section and the separation section together if the bond fails.

A reject port of a hydrocyclone has an orifice that is treated or coated to prevent blockage thereof when materials pass therethrough, such as produced water, asphaltenes, waxes, 'schmoo' or other materials having high potential for scaling. Such surfaces may include, but are not necessarily limited to, superhydrophobic surfaces and/or superoleophobic surfaces such as polytetrafluoroethylene (PTFE), fluorinated ethylene propylene (FEP), perfluoroalkoxy (PFA), tungsten disulfide (WS2), siloxanes, nanomaterials, surfaces created by diffusion of carbon into a stainless steel without forming chromium carbides (e.g. KOLSTERISING&#xae;), anti-scale treatment materials, and combinations thereof. The treated orifice may optionally be removable from the reject port.
